Ambry Genetics

May 05, 2023

The c.1376G>T (p.R459I) alteration is located in exon 6 (coding exon 5) of the CCDC181 gene. This alteration results from a G to T substitution at nucleotide position 1376, causing the arginine (R) at amino acid position 459 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
